Description
The Siemens 257-02038 is a 3-way pressure range control valve which is intended for use in regulating the HVAC systems. The flow coefficient of the pipe is 2. 0CV, this 1/2” valve has pressure control and thus suitable for several HVAC applications. The valve is made of brass material and the spring range of the valve is 3-8 PSI that means it can efficiently control the change in pressure within the system. This control valve is installed in HVAC systems for controlling the amount of fluid flow and pressure which is essentialfor the proper functioning of the HVAC system. This design makes it easy to install and manipulate the flow of the fluids within the system thus making the system highly flexible.
